It'll fire right up. I can drive it until it heats up to normal running temperature, then it wants to stall out. After it stalls it won't start until it sits for about 24 hrs. You can smell gas. I tried to start after it stalled and got it to start once but it was running with a miss. Sounded terrible and I had to hold the gas on or it would stall again. After holding gas down for 2-3 min it started to idle correctly. So I put in gear and it just died again. So I let it sit for a day and it started back up with no problem and I could drive again until it got hot again then it would stall. Injectors were replaced at 100000 and I replaced the plugs just recently. After I changed the plugs is when this started. I thought maybe I got a bad plug so I put the old ones in and it didn't make a difference. Ive cleaned the injecter connectors and checked fuses. I can't figure this out and its driving me crazy, especially with the warm weather arriving.

scan for codes and check fuel pressure with a gauge first....auto parts rent it.
